Chris Hemsworth turns 34 on Friday, and it really wouldn't be a proper birthday if his brothers didn't give him a hard time. The Thor: Ragnarok actor's youngest sibling, Liam, decided to wish Chris a happy birthday with a hilarious social media shout-out on Aug. 11. In addition to posting what appears to be a screenshot of Chris enjoying a bubble bath with a toy, he wrote, "Happy birthday Chrisso! Love u ya massive jerk ;) xox @chrishemsworth #bathtime #rubberducky." We love how close this family is.
